    I have interchanged gear sets from 25-30-35 hp and into the early 40 hp OMC’s in several motors. There are a few differences, but they will swap. I often swap out the keyed propshafts for the threaded propshafts so I can use a threaded prop nut. My 1954 25 hp has a 1957 35 hp gear set minus the pinion, of course. I’ve also only had one mismatched skeg section that wouldn’t mate.
